Linksys WRT54G running Tomato 1.19-mp2beta2

Hello,I just changed ISPs and this new one is having some serious uptime issues. I keep finding the internet down at random times, all the time. It could be thirty minutes at 08:00, then another 15 minutes at 09:15, then another 10 minutes at 11:30, then another 30 minutes at 19:00.

I want to keep track of how often this is happening to provide some data to backup a case against the service delivery from this ISP. Does Tomato have a log function that I can use to track this over a period of say, a week? Or a month? Or anything? Right now all I can see in the log option is a max of the last 100 lines, which doesn't suit my purposes.
